Instructions
Prepare the Pans
- Preheat oven to 350°F.
- Grease or line two 9×5-inch loaf pans.
Make the Batter
- In a large bowl, whisk together the all-purpose flour, white whole wheat flour, brown sugar, granulated sugar, cornstarch, baking powder, baking soda, salt, and cinnamon.
- In a separate bowl, whisk together the oil (or butter and oil), eggs, vanilla, sour cream, and sourdough starter until smooth.
- Fold the wet ingredients into the dry ingredients just until combined.
- Let the batter rest for 15–30 minutes.
Make the Streusel
- In a medium bowl, whisk together the flour, brown sugar, granulated sugar, cinnamon, and salt.
- Drizzle in the melted butter and toss with a fork until crumbly.
Assemble
- Divide half of the batter evenly between the two loaf pans.
- Sprinkle half of the streusel over the batter.
- Divide the remaining batter between the pans.
- Top with the remaining streusel.
Bake
- Bake for 50–65 minutes.
- Check at 45 minutes and loosely tent with foil if the tops are browning too quickly.
- A toothpick inserted into the center should come out clean or with a few moist crumbs.
- Cool in the pans for 15 minutes.
- Remove to wire racks and cool completely.
Glaze (Optional)
- Whisk together the powdered sugar and milk until smooth.
- Drizzle over cooled loaves.
Jessica's Notes
Prep Ahead
- Batter may rest in the refrigerator overnight before baking.
- Streusel can be made up to 3 days ahead and refrigerated.
- Loaves taste even better on the second day.
Storage
Store tightly wrapped at room temperature for up to 3 days or refrigerate for up to 1 week.
Freezer-Friendly
Freeze whole or sliced loaves for up to 3 months. Wrap well and thaw overnight at room temperature.
Variations
- Add 1 cup chopped pecans or walnuts to the streusel.
- Fold 1 cup blueberries into the batter.
- Add mini chocolate chips for a sweeter loaf.
- Replace the cinnamon with pumpkin pie spice for a fall version.
- Skip the streusel and glaze for a less sweet breakfast loaf.
